Application


The application of this Mutated Proteinase K is similar with wild type Proteinase K. But the mutated one has higher specific activity and more stable at RT. It is a broad substrate non-specific serine Proteinase. It is active over the pH range 4-11. It was used on any situation to digest native and denatured proteins. For instance, it is used for isolating mRNA or genomic DNA from different tissues and modifying glycoprotein for structure studies.Mutated Proteinase K is active with SDS, urea and EDTA and active between the temperature15-75ºC. Now,Proteinase K is a broad substrate non-specific serine proteinase. It was used on isolating mRNA, genomic DNA and digesting unwanted proteins during DNA and RNA preparations from different kinds of cells. It’s been used on glycoprotein modification and protein structure studies also. Proteinase K is active with SDS, urea and EDTA. Proteinase K is used for the isolation of native high molecular genomic nucleic acids. Enzymes like DNases and RNases from microorganisms and mammalian cells are rapidly inactivated by Proteinase K. Adding Proteinase K already during the cell lysis enables the isolation of highly native undamaged high molecular DNA or RNA. A variety of methods have been established, which are documented in numerous publications. Recently, Proteinase K has been used for the detection of BSE forming proteins which are uniquely resistant towards the enzyme's proteolytic cleavage. Proteinase K is very useful in the analysis of membrane structure by means of modification of proteins and glycoproteins on cell surfaces. Because of the cleavage specificity Proteinase K, characteristic fragments of proteins are obtained which are helpful in revealing the structure and function of proteins, particularly enzymes.

FAQ

Q1: Do you accept sample order?
A:  We will make samples before mass production, and after sample approved, we'll begin mass production. Doing 100% inspection during production, then do random inspection before packing.
Q2:  What information should I let you know if I want to get a quotation
A :  Quality you require, eg. Assay, Purity, or single impurity -Quantity you need -Standard you want, such as USP, EP, JP etc.
Q3: What’s your MOQ?
A :  Our MOQ is 1kg. But usually we accept less quantity such as 100g on the condition that sample charge is 100% paid.
Q4: Do you supply product report?
A : Yes. We'll give you product analysis report before shipping.
 Q5: What is our advantage?
A : The series of natural extracted product are all self-developed, produced and tested. Mature production technology, strict cost control, and perfect quality assurance system, ensure the product stability and competitive price.
Q6: When will you deliver the goods
A :  For sample(less than 1kg), in about 3 working days after payment; for larger orders (more than 1kg), in about 7 working days after payment.
Q7: How to confirm the Product Quality before placing orders?
A :  You can get free samples for some products,you only need to pay the shipping cost or arrange a courier to us and take the samples. You can send us your product specifications and requests,we will manufacture the products according to your requests.
